• Properties of potassium outward currents were investigated from 11 specimens obtained from patients with temporal lobe epilepsy. An IK but not IA or inwardly rectifying potassium currents, were observed in all cells Show Other
• The properties of outward currents were investigated with patch-clamp in acutely isolated cells at various postnatal ages and at adulthood (2-3 mo). Kinetic analysis and pharmacological properties showed that IK and IA were present in these cells. IA and IK remained stable with respect to kinetic properties during ontogenesis, but the relative contribution and pharmacological properties varied with age. IA dominated in P5-7 cells whereas IK was prominent in most older cells Show Other
